Slide locking device for multiple fasteners



Feb. 19, 1935. M. WINTERHALTER SLIDE LOCKING DEVICE FOR MULTIPLE FASTENERS I Filed Sept. 28, 1929 Zar /17' Patented Feb. 19, 1935 PATENT OFFICE FAS SLIDE LOCKING DEVICE FOR MULTIPLE TENERS Martin Winter-halter, Barmen-Wichlinghausen, Germany Kpplication In 4 Claims.

The invention has reference to multiple operated fasteners and particularly to the slide which serves for opening and closing such fasteners.

For the sliding motion of the slide there is, as

5 known, a movable handle set on a slide casing. It is also known to provide on such handle lugs for locking the slide, whereby such lugs work in conjunction with the fastener members in order to effect a stoppage of the slide in any position along the fastener members.

The invention consists in the particularly adapted formation of the bearing parts for the handle and in the satisfactory placing of the said locking lugs which is thereby simultaneously effected.

According to the invention the bearing parts for the handle are punched direct out of the front plate of the slide casing and bent upwards from theplate surface so that the bearing parts may result directly. In this way very simple conditions are provided for manufacture.

It is good for the purpose that two bearing parts are provided and, next to these parts, apertures in the front plate, through which the locking lugs can pass. In this way very simple conditions are provided for manufacture.

It is good for the purpose that two bearing parts are provided and, next to these parts, apertures in the front plate through whichthe locking lugs can pass. These lugs can be shaped in the manner of pins which will set between two of the locking members. But the lugs can also be shaped in the manner of reinforcements attached to the arms of the handle or slide-grip. At the same time such arms bear pegs for the bearings of the grip. The reinforcement pieces can pass through the'openings of the front plate slide, in plan view,

Fig. 4 shows a side view of the same with raised p. a d

Fig. 5 gives a side view with an altered exam ple of the rip- The slide casing consists of two plates at and b,

September as, 1929, Serial No. 395.985 Germany September 26, 1928 which are joined to each other, in some suitable manner, at their upper portion c. Between the two slide plates 0. and b there is introduced in the known way the locking members at of a break lock, alongside which the slide casing can slip in afterwards.

On the front plate there is set, in the known way, a turnable handle or grip e, which has at its upper extremity two lugs j which are bent at right angles outwardly and which fit into two corresponding bearings g which are punched out of the front plate a. Besides the lugs I there are bent out from the grip e, backwards, two pegs h, which, as shown in Fig. 2, can set between two locking members d as soon as the grip e has come into the position shown in Figs. 1-2. In order to insure the grips holding this position, there are further bent out from the front plate a, two knobs i, into which the grip can set and be resiliently held.

In the case of Figs. 3 and 4, the grip e has two arms 5. These arms at their inward extremity are so rolled as to produce respectively for each an eccentric-like part 74:. Further, the arms at this place are provided with lugs I which extend inwardly. These lugs seat in bearings m, which are bent from the surface of the front plate a upwardly after having been punched out of the plate in a manner to correspond; By bending these upwardly there are formed in the plate the openings 12 and through these openings the eccentric-like lugs k can pass in order, as is shown by the broken line in Fig. 4, to extend into and assume the locking position. The grip e is turned for this purpose in the direction of the arrowand the lugs k then take their place upon the locking members d, producing a locking effect.

In the case of Fig. 5 the locking action lug o is merely shaped as a protuberance; otherwise, the action and manipulation are the same as in the case of Figs. 3 and 4.

I claim:

1. A slide locking device for multiple operated fasteners comprising a slide casing, a slide handle, trunnions upon said slide handle, bearings for said trunnions formed by punching out portions of one side of said slide casing leaving openings therein with solid metal therebetween and lugs carried by said slide handle adapted to pass through the openings formed by punching out the bearings to lock said slide casing in any position along the fastener members.

2. A device as claimed in claim 1 in which the slide handle is provided with arms which carry said trunnions and said lugs are formed also upon said arms to serve as reinforcement members.

3. A device as claimed in claim 1 in which the bearings are formed by bending the punched out portions at right angles to the side 01' said slide casing.

4. A slide for multiple fasteners comprising a slide casing, a turntable slide handle, lugs on said handle having attaching arms for stopping the slide in any position along the fastener members, and bearin parts for said handle punched directly out ot the front plate of the casing and bent upwardly from the plate surface leaving holes therein with solid'metal therebetween, said lugs being arranged as reinIorcing pieces upon the arms of the handle and having bearing pins which engage the aforesaid bearing parts, and said lugs being arranged to pass through the holes in the front plate that have been made by punching out the bearing parts.
